By the nature of Autoconf, shell functions could possibly be implemented
via some sort of AS_FUNCTION_DEF hook that could create a function if
the shell supports it and an external script otherwise.  As long as the
external script directory was in the path, functions could be called
normally - no macro would be needed.

This would produce the best-case scenario when functions are supported,
but would only allow output strings and exit code to be retrieved from
functions.  Functions would not be able to reliably set shell variables.
